Well, every day is a school day. Here's a new valve. 152 valve july 84 635.jpg This is what the additional air valve should look like. Here's one of four broken valves, all of them look exactly like this: broken E12 valve.jpg This is the wrong one for the car, but the aperture visible is the same on...

magnet! I used the rare earth one from an old hard drive.

I missed this, Don! What an absolute joy it was to mess about with cars and enjoy such warmth and hospitality from your good self and Sheilagh in such a beautiful country. I'm very much hoping you're getting what all the fuss is about - the manual box absolutely transforms the car in my humble opini...

Thank you Nick, that is extremely reassuring. I am hopeful that I'm in the situation of having fixed a problem that may have been there beforehand with fuel pressure/delivery and am now dealing with bodges to bypass valve/afm adjustment done to mask rough running in the past. Now starts well, but ru...

Of course!

Many thanks,

Rob

It turns out this valve was not working, adding to start-up problems. Not seized, but not moving. using spare from an M635 results in starting straight up, but (as you'd expect) idle is high. Still stumbling until throat clears. Possibly a stupid question, but once it's established the disc isn't se...

It certainly should have, Don - it's new, but something's up. Starting much faster, but still running rough until "cleared throat". Am now in parts replacement bingo territory, but all doable. Have installed NRV to rule that out. Valve clearances done today new Bosch W8DC plugs today new i...

Thank you Phil, it appears to be a number of little problems adding up to a bigger one! Replacement ignition switch has made things more comfortable, too. Fuel pressure regulator problem #1, air slide valve #2, both appeared to be working normally in isolation, but change to less-worn spares improve...

Thank you Nick,

Yes - I understood it should stay above 2 bar overnight and drop over a longer period. This is internet wisdom, of course! You've reassured me knowing this is the right side of normal.

Cheers,

Rob

I have had to press the sixer into daily driver service until I get the sensible car repaired, which has brought a number of long-standing issues to the fore. Aug '84 build 635, so running the 018ECU, 018 AFM, brown low impedance injectors and the disc-type air slide valve. No in-tank pump, only mai...

I'm enjoying the same right now. If your car is the fine spline column then I'm pretty sure it's an easy job. The ignition switch is clipped to the back of the barrel. If it's the fine spline column, then the switch won't come out without grinding clearance to pass the webbing. Then it's just a case...

Following on from Ralph and others in looking at ways to change the ignition switch on a pre-? 1984 car, here’s the amount of webbing I had to remove in order to pull the switch out. Hope this helps someone out, I wrecked one of my spare switches like an idiot. There’s room to get a dremel in there....

I imagine the standard rhd manifold will fit - I've got a spare one in the shed from the upgrade to the Fritz system if there's a useful measurement or two you need.

Cold start valve/thermotime switch seems a likely place to look. It's a pain to get to, but easy to check once dragged out. The E28 Bentley manual is fantastic on this.

Pretty sure I've still got my original chain, will have a look.

I like this chap! I'm always surprised that the rear styling escapes the obvious criticism that the updating from the Series 1 meant the "funny ribbed bit" on Euro cars to hide the gap caused by the slimmer bumper. The Series 1 does look more resolved in this area, especially in a mint gol...

Happy Christmas to you all!

I knew this rang a bell from B35 / B34 swap searching!

I The OBC relay is know to fail and will prevent the car from starting. To bypass the OBC immobilizer, either: A) Jumper (bridge) the two green wires (pins 3 & 4) in connector C2 at the OBC relay box B) Jumper the Main Relay pins 30 to 87 & 87b with a Y-shaped wire. The OBC Relay box is loc...

I am afraid not - he is still struggling with maintaining focus.

He's always pleased to hear that so many people are still thinking of him (and benefiting from his knowledge and wisdom on this forum - and the bike forums too).

I wish we'd got more on this project - I was hooked!

Apologies chaps, I missed this. I saw him over summer and I'm afraid there hasn't been any progress physically, although his eyesight has improved a little. He was his wonderful, excited and affable self though, with time flying by. The Brucey brain was very much in gear - with ideas for a combined ...

Apologies if I'm misunderstanding the problem, but if your car is still moving with the brake pedal fully depressed then there is something very wrong with your brakes that requires immediate attention! Master cylinder? Is fluid leaking? I see you've changed out the pipes and - therefore - you must ...

Not sure if I posted elsewhere, but I followed 635Syd's suggestion and had the M manifolds and downpipes ceramic coated by Camcoat in the UK. Exactly as he said, the difference was amazing - it was just about possible to touch the manifold soon after shutting off the engine. Expensive, but absolutel...

Thank you,

I am in the fortunate position of having all four bolts present and correct: Sauber, you can make them out in the picture, but the four holes in your bootlid should clarify things!
